BAANCING Measuring points Measuring points are self-seale. Remove the cap an insert the probe through the seal. Draining Valves with raining for G1/2 or G3/4 hose connection. Valves without raining have a sleeve. This sleeve can temporarily be remove an a raining kit is fitte, which is available as an accessory. Setting Setting of a valve for a particular pressure rop, e g corresponing to 2.3 turns on the graph, is carrie out as follows: 1. Close the valve fully (Fig 1). 2. Open the valve 2.3 turns (Fig. 2). 3. Using a 3 mm Allen key, turn the inner spinle clockwise until stop. 4. The valve is now set. To check the setting: Close the valve, the inicator shows 0.0. Open it to the stop position. The inicator then shows the set value, in this case 2.3 (Fig. 2). Diagrams showing the pressure rop for each valve size at ifferent settings an flow rates are available to help etermine the correct valve size an pre-setting (pressure rop). Four turns correspons to fully opene valve (Fig. 3). Opening it further will not increase the capacity. Fig. 1 Fig. 2 Fig. 3 Valve close The valve is set at 2.3 Fully open valve 8
BAANCING Measuring accuracy The zero position is calibrate an must not be change. Deviation of flow at ifferent settings The curve (Fig. 4) is vali for valves with normal pipe fittings (Fig. 5). Try also to avoi mounting taps an pumps, immeiately before the valve. The valve can be installe with the opposite flow irection. The specifie flow etails also are vali for this irection although tolerances can be greater (maximum 5% more). Fig. 4 ± % 16 14 12 10 8 6 4 2 0 0 0,5 1 1,5 2 2,5 3 3,5 4 ) ) Setting, No. of turns. Fig. 5 Correction factors The flow calculations are vali for water (+20 C). For other liquis with approx. the same viscosity as water ( 20 cst = 3 E=100S.U.), it is only necessary to compensate for the specific ensity. owever, at low temperatures, the viscosity increases an laminar flow may occur in the valves. This causes a flow eviation that increases with small valves, low settings an low ifferential pressures. Correction for this eviation can be mae with the software TA Select or irect in TA-CBI. Sizing When Dp an the esign flow are known, use the formula to calculate the Kv-value or use the iagram. 9

Solution: Draw a straight line joining 1,6 m 3 /h an 10 kpa. This gives Kv=5. Now raw a horizontal line from Kv=5. This intersects the bar for DN 25 which gives 2,35 turns. NOTE: If the flow rate is out of the scale in the iagram, the reaing can be mae as follows: Starting with the example above, we get 10 kpa, Kv=5 an flow-rate 1.6 m 3 /h. At 10 kpa an Kv=0,5 we get the flow-rate 0,16 m 3 /h, an at Kv=50, we get 16 m 3 /h. That is, for a given pressure rop, it is possible to rea 10 times or 0.1 times the flow an Kv-values. 10
